Flash vrs Shockwave plug-in

[Arnold Gregory]

Where can I find good sources of pros and cons between Flash and 

Shockwave plug-ins, including current (Macromedia's latest is 6 mo. 

old)  statistics on the deployment of each. I need to include some 

backup documentation in a presentation to a potential client. I need 

to recommend one or the other. I like Flash but I am more familiar 

with Director.


How do I convince a client that visitors will take the time to 

download another plugin to view their materials.


Thanks in advance.
